Walmsley Brook

Walmsley Brook (named for John Walmsley, a settler in the Leaside area)
started as two small streams near Duplex Avenue and Alexandra Boulevard, which
joined west of Yonge Street and flowed SW to Mount Pleasant Road and Broadway
Ave. From there it flowed in a generally easterly direction past the corner
Bayview Avenue and Eglinton Avenue to meet the West Don River in Ernest
Thompson Seton Park, just north of Overlea Boulevard. It was approximately six
kilometres long and had one and a half kilometres in two tributaries. Walmsley
Brook is divided into three reaches in this account: Broadway
Reach, from its source to Bayview Avenue; Leaside
Reach, to the CPR Railway; and Power Lines
Reach, from the CPR to where it joins the West Don River.
Elvina Stream, a small tributary, which joins the
Broadway Reach just east of Mount Pleasant Road, and Northlea
Stream, joining Leaside Reach, are briefly described.
